I have been trying to install excel: ^1.1.5 version. But all I am getting this error.
Because excel >=1.0.4 <2.0.0-null-safety depends on xml ^4.1.0 which depends on convert ^2.1.0, excel >=1.0.4 <2.0.0-null-safety requires convert ^2.1.0.
And because `json_serializable` >=4.0.3 depends on build ^2.0.0 which depends on convert ^3.0.0, excel >=1.0.4 <2.0.0-null-safety is incompatible with `json_serializable` >=4.0.3.
And because invoiceninja 0.0.9 depends on `json_serializable` ^4.1.0 and no versions of `invoiceninja` match >0.0.9 <0.1.0, excel >=1.0.4 <2.0.0-null-safety is incompatible with `invoiceninja` ^0.0.9.
So, because `etf` depends on both `invoiceninja` ^0.0.9 and excel ^1.1.5, version solving failed.
pub get failed (1; So, because `etf` depends on both `invoiceninja` ^0.0.9 and excel ^1.1.5, version solving failed.)

I've activated Dart non-nullable syntax experiment in my pubspec.yaml file:
name: tests
description: A new Flutter application.
publish_to: 'none'
version: 1.0.0+1
environment:
sdk: ">=2.9.0-21.0.dev.flutter <3.0.0"
analyzer:
enable-experiment:
- non-nullable
dependencies:
flutter:
sdk: flutter
cupertino_icons: ^0.1.3
dev_dependencies:
flutter_test:
sdk: flutter
flutter:
uses-material-design: true
So, now after running flutter pub get I'm trying to create a class using non-nullable syntax:
class Component_Decorator_A extends Component_Decorator {
Component_Decorator_A([Component? component]) : super(component);
#override
operation() {
component?.operation();
print('Component_Decorator_A.Operation()');
}
}
Quite surprisingly, syntax analyzer in Android Studio says:
This requires non-nullable language feature to be enabled. Try updating your pubspec.yaml to set the minimum SDK constraint to 2.9.9 or higher, and running pub get.
Ok, I cannot set the minimum SDK version to exactly 2.9.0 as suggested, as far as each time I try to set environment: sdk: ">=2.9.0 <3.0.0" in my pubspec.yaml, the subsequent flutter pub get leads to the next version solving error that I was unable to resolve:

Would you please suggest me what should be done to make Dart non-nullable syntax steadily usable in Android Studio (latest version)?
I think this issue was being resolved with the new version. The migration guide for null safety is out now a mentioned in this comment:
Please read https://dart.dev/null-safety/migration-guide. You can't
just turn on null safety. We have docs and migration tooling available
for you!
And if it still doesn't work, try the suggestion here:
You should increase your current sdk version from sdk: ">=2.7.0
<3.0.0" to sdk: ">=2.12.0 <3.0.0" and run flutter pub get. If you
don't want to do that manually, you should run dart migrate --apply-changes in terminal. I recommend the second one
I'm setting up an android project from another company which involves selfmade C++ cross platform libraries. For an older version of these libraries an complete app project was made in java with a jni interface to access these libraries, which are stored as their own modules with gradle.build files. The goal is to get the app compiling for arm64-v8a architecture because of the Google requirements for app update.
The project is set up with:
gradle experimental plugin 0.11.0
gradle plugin 4.1
boost 1.64.0 for armeabi-v7a (got arm64-v8a precompiled libraries as replacement)
opencv 2.4.13.2
ndk r15c
I checked all dependencies for getting a arm64 pendant, which was only needed for the boost dependencies.
I tried changing the ABI list which is used for every project to include all architectures or all seperatly. I tried using other ndk versions. What might help but i didn't accomplish was changing the experimental gradle plugin to the normal plugin but i couldn't get that right.
I expected some compiling or linking errors but it only tells me "ABI filter 'arm64-v8a' is no longer supported in NDK version r15.2.4203891.". If i try other architectures i get the same error, but instead of the 'arm64-v8a' the current selected architecture. If i give an invalid architecture it changes to "Target ABI 'hello' is not supported.", so it recognizes the architecture i think.
Stacktrace of first error:
A problem occurred configuring project ':app'.
Exception thrown while executing model rule: NdkComponentModelPlugin.Rules#configureNativeLibrary(ModelMap, NdkConfig, NdkHandler, ModelMap, File, ServiceRegistry) > create(livestage) > withType()
Exception thrown while executing model rule: NdkComponentModelPlugin.Rules#configureNativeLibrary(ModelMap, NdkConfig, NdkHandler, ModelMap, File, ServiceRegistry) > create(lib-jni-cxx) > withType()
Exception thrown while executing model rule: NdkComponentModelPlugin.Rules#configureNativeBinary(BinaryContainer, ModelMap, NdkConfig, NdkHandler) > withType()
ABI filter 'arm64-v8a' is no longer supported in NDK version r15.2.4203891.
The experimental plugin hasn't been supported for years, so it's no surprise that it doesn't work. Migrate to externalNativeBuild: https://developer.android.com/studio/projects/add-native-code
Currently I'm trying to upgrade a Xamarin.Forms project to use .NET Standard 2.0. This went fine for Android but I'm getting stuck with the iOS version. To build iOS we use a On-Primise MacMini as build agent int VSTS. Now I'm getting the error below when building the solution.

=================================
This output comes from the following build definition:
Now I've searched the internet and found a view possible solutions:
Update Visual Studio on the MacMini
Update XCode on the MacMini
Install .NET Core 2.x SDK on the MacMini
Add .NET Standard 2.x NuGet package to Xamarin.IOS project
Add .NET Standard Library NuGet pre-release package to Xamarin.iOS project (not possible)
Manually reference netstandard.dll to the Xamarin.iOS project
Remove install argument (not using it)
But all of this was not enough to fix the issue. Now I'm not a expert in using a Mac. Actually I never touched one before this issue... So I might have done something wrong here...
But I've been able to get some version information about all products on the MacMini:

Everything started to work fine after we manually edited the .NET Standard 2.0 project file (*.csproj) and add a PackageReference by hand.
<ItemGroup>
...
<PackageReference Include="NETStandard.Library" version="2.0.0" />

I tried downloading the trial version of monotouch from the website but all the links were broken.
So I downloaded the following by digging from google.
()MonoDevelop-3.0.3.5
()MonoFramework-MRE-2.10.9_11.macos10.xamarin.x86.dmg
(*)Monotouch-eval-5.1.0.pkg
but after doing so when I run a sample ios app from the xamarin website only then it fails to build -> not being able to compile to native code.
This is error log.

Monotouch-eval-5.1.0.pkg
This is an pretty old, beta version of MonoTouch.
MonoTouch 5.2.12 is the current stable release while 5.3.5 is the current unstable release.
No gcc compiler found
This means no C compiler was found. In general you should make sure your MonoDevelop preferences (SDK Locations) are set the point to your Xcode installation directory.
However in this case I think your MonoTouch version is too old to work with Xcode 4.4. Updating your evaluation version to 5.2.12 is the first step you should try to fix this.
Below is the manual installation for MonoTouch evaluation which FINALLY works!:
Download and install packages listed below, in the order given:
1) Mono: http://download.mono-project.com/archive/2.10.9/macos-10-x86/10/MonoFramework-MDK-2.10.9_10.macos10.xamarin.x86.dmg
2) MonoDevelop: http://download.xamarin.com/monodevelop/Mac/MonoDevelop-3.0.dmg
3) Eval MonoTouch: http://download.xamarin.com/priv/d6d0ad447c01dd2bbbbbba829f6e1a/MonoTouch/Mac-eval/monotouch-eval-5.2.11.pkg
For the above mentioned environment this combination works like magic.
Just hope that they'll fix the broken links on their site too or else many other newbies would continue to get discouraged.
Thanks to support people of Xamarin who shared these links.
I'm trying to compile an install shield project. It's a 64 bit program.
I keep getting this error, although it does compile OK and installs OK:
Error 16 -6058: Error merging Visual C++ 10.0 CRT (IA64) with module ID C:\Program Files (x86)\Common Files\Merge Modules\Microsoft_VC100_CRT_ia64.msm ISEXP : error : -6058: Error merging Visual C++ 10.0 CRT (IA64) with module ID C:\Program Files (x86)\Common Files\Merge Modules\Microsoft_VC100_CRT_ia64.msm
Any idea how can tell it NOT to try and merge ? (I can let it install the CRT ad a redistributable instead)
Ok, so it's like this:
Was detected as a dependency by mistake:
Adding merge module 'Visual C++ 10.0
CRT (IA64)' that is a dependency of
component
'MyProjectName.Primary_output'
So you go to:
Specify application Data -> Files
Right click on the specified project that had the dependency.
Choose Dependencies from scan at build.. find that unwanted file, and uncheck it.
Some Installshield products (2010, 2011 at least) appear to have an issue scanning managed (/clr) c++ modules that use the 10.0 CRT, even for 32-bit-only projects. In those cases the IA64 msm gets added to the project, producing "error -5008: Intel64 or AMD64 must be specified in the template of the Summary Stream". Yochai's fix cured that too. I have not seen this issue for native c++ code.
